How to Reduce LLM Token Costs by 85%
A practical guide to semantic compression — how it works, when to use it, and how to integrate it into your AI workflow without sacrificing output quality.
The Token Cost Problem ¶
Every LLM API call costs money. GPT-4, Claude, and Gemini all charge per token, and context windows are getting larger, not cheaper. A typical coding agent session can burn through 100K+ tokens per task.
The math is simple: if you can compress your context by up to 85% without losing meaning, you save up to 85% on token costs.
What is Semantic Compression? ¶
Semantic compression goes beyond simple text truncation. Instead of cutting text at an arbitrary character limit, it:
The result reads naturally and preserves the information an LLM needs to produce high-quality outputs.
Getting Started ¶
1. Create an account
Sign up at gotcontext.ai. The free tier includes 1,000 compressions/month.
2. Generate an API key
Go to your dashboard settings and create a new API key.
3. Connect via MCP
Add to your Claude Code config:
``json
{
"mcpServers": {
"gotcontext": {
"url": "https://api.gotcontext.ai/mcp",
"headers": {
"Authorization": "Bearer gc_live_YOUR_API_KEY"
}
}
}
}
`
4. Start saving
Your AI tool will now automatically have access to compression tools. Add a note to your CLAUDE.md:
`
When context is large (>10K tokens), use gotcontext's ingest_context tool to compress before processing.

Real-World Results ¶
| Document Type | Original | Compressed | Savings |
|---|---|---|---|
| API documentation | 7,200 tokens | 1,440 tokens | 80% |
| Source code (500 lines) | 4,200 tokens | 1,260 tokens | 70% |
| Large codebase (50 files) | 48,000 tokens | 7,200 tokens | 85% |
